Waste Rock Pile <br />The proposed waste area will be located on the western most slope of the <br />permitted area on top of the previously reclaimed mine waste area. The slope <br />here is quite steep so it will be terraced into two narrow benches, one above the <br />other (see Exhibit C labeled "waste rock pile "). Currently there is little to no <br />topsoil here so there will be no need to strip this area before dumping begins. As <br />stopes become mined -out, as much waste rock as possible will be gobbed in the <br />mined -out stopes. Thus, it is expected that the surface storage area will be <br />sufficient for all future mining operations and there will be no need for expansion <br />of the waste rock pile. The pile will be stacked to a height that will not impede <br />grading of 2:1 during reclamation. <br />Berms and ditches will be constructed around the waste rock pile to divert <br />stormwater away from the waste pile. A runoff basin will be constructed <br />downhill and adjacent to the waste rock pile to catch any surface runoff coming <br />off the piles (see Appendix II for a complete description of the Drainage Design <br />Plan). <br />b. Ore Stockpile <br />The ore stockpile will be located on the second tier of the waste rock pile <br />approximately 80 feet west of the portal. Currently there is no ore stored on site. <br />During active mining the ore will be piled up to a workable stockpile and hauled <br />to the mill using a first in, first out system. Ore will be stored onsite for no more <br />than 30 days after mining operations cease. <br />Design components (BMWs) will be employed to prevent cumulative collection <br />and infiltration of potential constituents of concern into the substrata. These <br />design components include a clay liner, limited contact time, and surface water <br />controls (ditches and berms). (For a description of the ore pad liner, see <br />Exhibit T - EPP). <br />C -4 <br />
